Understanding Concepts in Math Textbooks Numbers + Arithmetic + Circles + Right Triangles (4 Book Series)

Why is math so difficult? Part of the reason is that all of the math we learn in grade school is cumulative and connected. For example, the logarithms we learn in high school are dependent on the exponents we learn in middle school, and the exponents we learn in middle school are dependent on the multiplication we learn in elementary school. The problem is math textbooks assume complete knowledge of previous topics before explaining new concepts. Yet there are few students who are able to remember all of what they learned a couple months ago, let alone several years ago.
 
This series, Understanding Concepts in Math Textbooks, organizes and connects the various concepts learned throughout grade school. It covers the four main topics of math textbooks: numbers, arithmetic, circles, and right triangles. Although the mathematical concepts for each topic are organized separately, each book in the series explains in detail the connections between each concept so that the reader is able to see the big picture. These books cover math concepts from elementary school, and are geared toward students preparing to enter middle school.

1. Complete and comprehensive explanations of each topic
2. Explanations of the connections between concepts
3. Accessible to everyone, regardless of math ability
4. Contains fun stories that promote a love for math
